Abstract
A pressure measuring system is provided in which a closing element supported in the pressure fitting channel is activated or displaced by a pressure surge or a pressure wave and thereby seals the channel to the measuring element and thus prevents an outflow of the fluid.
Claims16
A pressure measuring system comprising:
- a pressure fitting;
- a measuring element connected to the pressure fitting pressure-tight, the pressure fitting having a pressure channel on an inner side, which is connected pressure-tight to the measuring element an evaluation or signal transmitter;
- a movable closing element arranged in the pressure channel that seals the pressure channel when the pressure or volume rises;
- and
- a guide part, the guide part being a hollow, piston-shaped body,
- wherein the closing element is disposed entirely inside of the hollow, piston-shaped body and the hollow, piston-shaped body is arranged inside of the pressure channel.
